SPECIFICATION forming part of Letters Pate-nt No. 320,006, dated June 16, 1885.

Application filed May 23, 1884. (No model.) Patented in Canada July 25, 1884, No. 19,858. I

'To @ZZ whom it may concern:

and I do hereby declare that the following is a A full, clear, and exact description of the same.

The invention relates to certain new and useful improvements in cloth-pressing machines; and it consists in the peculiar combinations and construction and arrangement of parts hereinafter more fully described and claimed.

Figure l is a sectional side elevation of the machine, taken through the line x y of Fig. 3, showing the toggle -joints broken. Fig. 2 is an outside elevation of the machine, showing the toggle -joints straightened, but with the damping and winding rolls removed. Fig. 3 is a view in horizontal section on the line x x of Fig. l. Fig. 4 is a detail of the togglejoint. Fig. 5 is a perspective detail of the wiper. Fig. 6 is a detail, showing an equivalent arrangement for breaking the togglejoint. Fig. 7 is a section on the line y y of Fig. 2, looking in the direction of the arrow, showing the means by which I hold the pressingplates apart when the toggle joint is broken.

A, B, C, and D are four hollow plates, supported by the four columns marked E. The bottom plate, D, rests on the collars a, formed on the columns E, and may be moved up vertically on the said columns. The plates A, B, C, and D are connected together, so that when pressure is directed upwardly against the lower plate, D, the inner surfaces ofthe four plates come together, the pressure exerted on these surfaces thus brought together being regulated by the strength of the springs F, placed one on each of the columns E between the uppermost plate and a nut, F, on the end of each column.

When the pressure is removed from the bottom plate D, it will naturally drop back onto the collars a, and the other plates will ofcourse follow; but the downward motion of the top plate, A, is arrested by coming in contact with a shoulder, e, formed on each of the columns E, which shoulder is made by reducing the diameter at the top of the column, as indicated in dotted lines in Fig. l.

The other plates are supported vby an arrangement which forms a part of my invention, and I have therefore shown it in detail in Fig. 7. In this figure it'will benoticed that the three plates A, B, and C are each provided with a stud, G. Four studs G are provided on each plate, one near each of the four corners of the plate, and each stud is provided with a head, through which a hole is made, to permit the passage of a vertical spindle, H. The spindle H, passing througheachof the vertical rows of studs on the corresponding corners of f plates A B C, is securely held to the stud G on the top plate, A, by nuts b, as indicated. The spindle passes through holes made in the other studs sufficiently large to permit of the free vertical movements of the studs on the spindle H. The effect of this arrangement is, that when the lower plate, D, comes in contact with the plate C this latter plate is raised till it comes in contact with the plate B, which in its turn is moved upwardly till it comes in contact with the plate A, when all the plates move together as far as they are permitted to do so by the springs F. In thus moving up,the studs G,attached to the plates B and O, move freely on the spindle H till the top plate A is touched, when the spindles move with them. The removal of the upward pressure from the plates causes them to fall .until their studs come in contact with the nuts c, which nuts can be readily adjusted so as to increase or decrease the distance of the openings between the plates.

The upward motion to the plates is derived by the straightening of the toggle-joints formed on the four pairs of arms marked I, which are located substantially as shown in the drawings, and the toggle in each of the arms is what is commonly known as a knifejointz'. e., onel arm is provided with a shoulder, t', against which alateral projection, i, of the other arm impinges when the arms are in alignment, as shown in detail in Fig. 4,

sothat the cams J which operate them cannot push them past the point where their centers are on a line. On reference to Figs. 1 and 2 the action of the cams'J will be understood.

In Fig. l the toggle-joints are shown broken,

the iiat sides of the cams J being oppositeto;

the joints. In Fig. 2 the toggles are 'shown arms out of contact with the cams J. It will be observed that a portion of each cam J eX- tends beyond the rest, as shown at j', 'by means of which the toggle is straightened, and when said portion j has passed the roller d the cam no longer bears on the roller, thus reducing the power necessary to operate the machinery to a minimum. l

With the viw'of drawing back the arms o for the purpose of breaking the toggle-joint, when it is desired to open the spaces between the plates, I provide for each pair of joints a pivoted bar, K, which is connected to Vthe rod e', connecting the joints by the chain L. For 5 each bar K, I provide a wiper, M, which is keyed to the same shaft, S or V, as the cams J on the corresponding end of the machine are fastened to. These wipers are arranged to come in contact with their respective bars K o at the moment when it is desired that the toggle-joints should be broken, when by pushing over the-said bars K into the position shown in Fig. 1 the desired effect is produced.

N is the main driving-shaft, provided with 5 suitable driving-pulleys, O, and withapulley, P, to drive a fan, when one is used in connection with the machine.

Q is a worm-pinion, keyed or otherwise fast-l ened to the shaft N, and arranged to mesh with o the spur-wheel R,which is keyed or otherwise fastened to the shaft S, on which two of the cams J and one of the wipers M are fastened, as shown. On the opposite side of the shaft S is keyed or otherwise fastened a spur-wheel, 5 T, which meshes with the spur-wheel U, keyed or otherwise fastened to the shaft V, on which the other two cams and the other wiper are fastened.

On reference to Figs. l and 3 it will be no- 3 ticed that the other moving parts ofv the machine also derive their motion from the shafts S and V, the operation of which I shall describe immediately; but before doing so II wish to draw attention to the device shown in Fig. 5 6, in which an eccentric, W, is indicated as a substitute to take the place of wiper M. This eccentric we will assume is keyed to the shaft S, and is connected to the pivot-rod e of the toggle-joints by a strap, w, and rod w', as indicated. As the eccentric W is set the same as the wiper M, the revolving of the shaft on which it is attached will act on the toggle-joint in precisely the same manner, and therefore such eccentric and strap may be used as an equivalent for the wiper lever and chain before referred to. y

X is a damping-roller driven from the shaft V by the sprocket-chain v', passing over a wheel, V', keyed to the outer end of the shaft V, and sprocket-wheel W', keyed to the outer end of the shaft of the damping-roller, as indicated. This roller revolves in a trough of water, as shown, and is intended to damp the cloth before it is carried between the pressingplates. The dotted line Y represents the cloth. This it will be noticed rst passes around the ltension-bars Z, then around a roller, f, over the damping-roller X, then under the small roller g, and then up over a take-up roller, h, which latter roller is driven from the damping-roller X by the belt p. From this latter roller it passes up over the small roller i, (see Figs. l and 3,) thence between the two plates C and D, and then around the small roller j at the opposite end of these plates, and back again between the plates Band C, then around the roller 7c, back between the plates A and B, over the roller Z, down to and below the winding-roller m, which latter roller derives its motion from the shaft S through sprocket-wheel S', sprocket-chain s, and spur-gearing n n, as indicated in Figs. 1 and 3. The cloth Y, in passing around the roller m, hugs it sufficiently tight to be drawn forward by its motion,when the plates A B C D are open, but when closed the winding-roller on. will revolve without in any way tearing or straining the cloth.

o is a cloth-roller, on which the cloth is finally wound. This roller lies loosely in the position indicated in Fig. l, and derives its motion from direct contact with the windingroller m. The cloth as it winds upon the said -roller increases it in diameter, but as it has no positive driving-gear of itself the said increase in diameter is compensated for by the roller o slipping on the roller m.

It is my intention to heat the plates B, C, and D by steam or hot watersupplied thereto from any suitable source through the pipe B', while the top plate, A, I intend to keep cold by filling it with cool water supplied through the pipe A.

By carrying the cloth first between the two plates C D and then between the two plates B C, I obtain a double hot pressure for the cloth, while by then carrying it between the two` plates A B, I cool the cloth by a cold pressure caused by the cold-water plate A.

Although any one familiar with the pressing of cloth will from the foregoing description and on examination of the accompanying drawings understand the operation of the machine, I may as well explain that the jointed arms I are arranged and operated to bring the plates A, B, C, and D together at stated regular intervals, to hold the cloth between them under pressure for a certain period, and then to fall back, so as to leave open spaces between the plates, when, by the action of the winding-roller m, the cloth is drawn through the plates for a given distance, when the operation is repeated. Y

As the damping-roller X is revolving conit, it is necessary to keep the cloth moving; otherwise the cloth will become damper at some spots than at others.. In order to accomplish this motion during the timethat the plates are held together,I provide the take-up roller h, which in revolving draws the cloth from the damping-roller, carrying the cloth somewhat `into the position it is shown in in Fig. 1.

Vhat I claim as my invention is- 1. The combination of the hollow plates A,

tinuou sly, and the cloth always remains against IOO IIO

B, C, and D, the columns E, the springs F, and nuts F', arranged as specified, the arms I, connected to plate D,and provided with knifejoints, as described, the cams J, and mechanism, substantially as described, for operating said cams, substantially as and for the purpose specified.

2. The combination of the driving-shaft N, Worm-pinion Q, the spur-Wheel R, shaft S, the spur-Wheels T and U, and the shaft V, with the cams J, the toggle-jointed arms Lthe pressplates operated by the said arms I, the Wipers M, the bars K, the rods e, and the chains L, substantially as and for the purpose specified.

3. The combination, with the cloth-pressing plates C and D, supports for the same, the toggle-joints I, cams for operating said togglejoints, and means for rotating said cams, of mechanism acting independently of said cams, substantially as described, to break the joints, as set forth.

4. The combination of the top plate, A, plates B C, and the columns E, having shoulders e formed thereon, with the studs G, at-

tached to plates A B C, the spindles H, pass- 25 ing through holes made in said studs G, and the nuts b and c on said spindles, substantially as and for the purposes specified.

5. The cloth-pressing plates, means, substantially as described, for intermittently op- 3o erating said plates, the Winding-roller m, the roller X, for continually damping the cloth before its passage between the plates, and mechanism, substantially as described, for rotating said rollers, in combination with the 35 guide-rollers t' j k,and the roller h, and means, substantially as described, for continuously driving the same to draw the cloth from said damping-roller during the time that the plates are held together,as and for the purposes here- 4o inbefore set forth.
